QtMultimedia using QML Video play is not working

Kallappa M B

Hello,
I am trying to play a video on Raspberry pi-3 and Made cross compile setup on Linux host machine and the problem is video play is not working on Raspberry pi but the same code will work on Linux machine.
Also i have tried the Qt widget example for video play, it is working fine.
and the qml code is here

import QtQuick 2.12
import QtQuick.Window 2.12
import QtMultimedia 5.12
import Directory 1.0

Window {
visible: true
width: 640
height: 480
color: "#000000"
title: qsTr("Hello World")

Rectangle {
    id: rectangle
    width: 400
    height: 246
    color: "#00000000"
    border.width: 7
    border.color: "#8a8b91"

    MediaPlayer {
          id: player
          source:  "./foggy_road_timelapse_256.webm"
          autoPlay: true

    }

    VideoOutput {
        id: output
        anchors.fill: parent
        autoOrientation: true
        source: player
    }
}

}

For this only blank screen is coming in Raspberry, Kindly suggest where i am doing wrong

Hi,

Did you deploy that video file on your device in the save folder as your application ?

@SGaist

VideoOutput {
        (...)
        anchors.fill: parent
        (...)
    }

It clearly says that yes, he deployed to the same folder as app. So I dont understand your question. Was it meant to substitute your lack of knowledge?

First thing: please stay polite.

As for the question I asked to @Kallappa-M-B, no it does not say that. Especially in the part you are quoting.

Code does not ensure that the file is available anywhere.

In the case of @Kallappa-M-B, the video path is "./foggy_road_timelapse_256.webm" which means that it is relative to the executable path. @Kallappa-M-B is cross-compiling his application. At no point does he mention that he also copied the file over to his Raspberry Pi-3 in the same folder where his application resides on the device.

thanks @SGaist
Yes i have kept Video file in the same folder in Raspberry-Pi

SGaist

Does it play correctly if you do that using GStreamer directly ?

@SGaist
No i haven't tried the way you mentioned and Kindly let me if any methods to test i am new to to this

SGaist

The idea is that you try playing your video using the GStreamer command line tool as GStreamer is used as backend on Linux for multimedia related stuff.
